Health Roundup: Omega 3, shopping, 'smell' test, anesthesia, salt, cancer inhibits Alzheimers and blood test predicts how you will age

Taking omega-3 fish oil supplements may increase the risk of aggressive prostate cancer by 70%

Fish-oil supplements are said to protect against heart attacks and strokes, stave off arthritis, boost brain power and prevent behavior disorders in children.

However, scientists found that those with the highest levels of omega-3 in their blood were 71 per cent more likely to develop fast-growing, hard-to-treat prostate tumors. They were also more likely to contract the slower, less deadly form of the disease, with the overall prostate cancer risk raised by 43 per cent.

Who knew?  Women burn 15,000 calories a year shopping: Annual retail therapy sessions equate SEVEN marathons (but one in ten shoppers polishes off 1,000 calories per trip)

How having cancer can protect you from Alzheimer's: Risk of the brain disease is 35% lower

Older people with Alzheimer's disease are less likely to develop cancer, and those with cancer are less likely to develop Alzheimer’s, scientists have discovered.

A study of more than 200,000 people - the largest of its kind - showed the risk of an Alzheimer’s patient developing cancer was half that of an elderly person without the condition.  They also found that having cancer made a person 35 per cent less likely to develop Alzheimer’s.

The test that can 'smell' bladder cancer long before symptoms develop and is 100% accurate

Bladder cancer can now be detected long before symptoms develop - after scientists created a device that can smell the disease.
Responding to chemicals in a patient’s urine, the sensor is able to give an accurate diagnosis within 30 minutes.

The revolutionary blood test that could predict how long you'll live, what ailments you'll get - and how fast you'll age

A revolutionary new blood test could tell you how long you will live, and how quickly you will age.  Scientists have discovered a chemical ‘fingerprint’ in the blood that may provide clues to an infant's health and rate of aging near the end of life.
The discovery raises the prospect of a simple test at birth that could help doctors stave off the ravages of disease in old age.

It could lead to the development of powerful new treatments for age related conditions such as bone problems and heart disease.
Scientists identified 22 metabolites, small molecules linked to metabolism, that may be useful indicators of how we can expect to grow old.

One in particular, linked to a range of traits including lung function, bone density, blood pressure and cholesterol levels, was singled out by the researchers.

How a general anesthetic could harm your memory for life: Research finds that three quarters of older patients develop memory loss after surgery

Significant numbers of patients have long-lasting behavior changes. A study shows that general anesthesia may increase the risk of dementia and it could even weaken the immune system. The longer the surgery and the older you are, the more you're at risk

Rare Mutation Ignites Race for Cholesterol Drug

The discovery of the mutation and of the two women with their dazzlingly low LDL levels has set off one of the greatest medical chases ever. It is a fevered race among three pharmaceutical companies, Amgen, Pfizer and Sanofi, to test and win approval for a drug that mimics the effects of the mutation, drives LDL levels to new lows and prevents heart attacks. All three companies have drugs in clinical trials and report that their results, so far, are exciting.

CDC says Americans still consume too much, but studies show no benefit in reducing salt

Basically, the report says that consuming anything between 1-½ and 3 tsp of salt per day is just fine, and there were adverse effects from eating more than that or less than that.
